Enjoyed staying here, with a couple of caveats:

1) It's near BTS... yes, the tracks. The tracks are in front of the building. However, the building is roughly halfway between two stations... meaning that you need to walk 10-15min to get to the more convenient of the two stations. For me, this was super inconvenient since I was sweating by the time I was at the station from the Bangkok heat. When it rained, the roads were flooded and I had to walk through 5-inches of water to get home. This somewhat removes the benefit of being "near BTS", although it's only 10-15 minutes away.

2) The internet was very slow and unreliable while I was there, although Rattana said she'd fix it for future guests. YMMV. — I had to tether internet from my phone for part of my stay since the wireless was so slow at that point that it was completely unusable.

3) I had some minor mechanical issues but she fixed those. Not sure if she was aware of them before I pointed them out. I generally pay attention to stuff that is broken, but other guests might not. I tried to relay any information that I could back to her, but other people might not take as much care and I'm not sure how often she actually visits the apartment to check if everything is working properly.

With that said, the snacks that she left were very thoughtful and delicious, she was responsive over Airbnb messages (thanks!), everything was pretty clean including the bed and towels, and I was comfortable besides the issues noted above. Not sure if I'd stay again due to the distance to the BTS stations, but it's not bad either.
